The simplest antenna you can make/install? Run a speaker wire out the window and clip it on your radio – and you are in business. I have used random wire antennas almost exclusively since the early 1960’s – they are simple /cheap/easy – and they work!
If you want to do a wire right – there are some things to consider . . .
What to do with both ends – temp or long term – how far off the ground – has to be at least high enough to be out of the way!
This is my solution to a long term / permanent random wire . . .
It attaches to the 4×4 that the rotator / loop antenna combo lives on @ about 13 feet off the ground . . .
The wire runs roughly east / west – about 38ft 4inches – between the insulators – ends at about 11 feet or so above the ground . . .
Simple TV antenna mast stand offs – the siding on the shed is an OSB product – no real strength there to attach to – so I went inside and glued and screwed some 2×4 pieces to screw into – yes – it is over built – I could easily put a 10 foot mast on there and hang another antenna at the top if I wanted to deal with an 85 foot run of coax . . .
So – when the wire gets to the mast it goes to an LDG 9:1 UNUN – long story short ( and very simplified )- a random wire antenna has roughly 450 ohms of resistance . . . ( But Bruce – the antenna wire only has one end – how can it possibly have 450 ohms of resistance? – this is “neither the time nor the place” to dive head first into THAT explanation – there are numerous electrical and radio theory courses out there on the internet – Duck Duck Go is your friend . . .)
. . . and the UNUN converts that to approximately 50 ohms – which is what your radio is wanting to see. The antenna wire attaches to the positive side and your ground side goes to your ground rod.
Then run a ground wire from that ground rod to the ground rod below the entry box – then ground your lightning / surge suppressor to the ground in your entry box – the ground is common to the coax ground side.
The random wire suppressor is on the lower right in the entry box and everything is grounded to everything and goes straight down to an 8 foot ground rod under the box – both ends of the coax are grounded to an 8 foot ground rod and both of those rods are tied together with 6 gauge single strand copper. So – – – that the electrical potential at both ends of the coax run are plus or minus the same – as well as any stray RF energy picked up by the shielding on the coax is bled off by grounding at both ends – seal all your exposed connections ( use something along these lines ) making sure they are correct before you seal them since most products of this type really don’t like coming apart – LOL . . .
Or you can hang a piece of speaker wire off the balcony or run it out the window – LMAO!
And that is the neat part of this hobby of SWL ( Short Wave Listening ) – it can be pretty much as simple or involved as YOU want to make it to be – to YOU.
And other random radio stuff – if I can ever figure out how to configure and run SDRCONNECT correctly – I’ve actually had it running twice and have crashed it more times than I will admit to – then I “should” be able to use my AIRSPY – or – yet another SDRPLAY device and a separate internet connection – room for 8 users – at 10 bucks a month per head that will almost pay for the internet needed to send it out to the world – at some point I would have to figure out which antenna on which days – I haven’t gotten that far with it yet – I’m not sure a remote user can pick an antenna to use even with the nRSP-ST networked radio receiver – but that would be a elegantly simple solution – almost a plug n play thing. Does anybody out there remember “plug n pray” with windoze from years ago – what an ongoing train wreck . . .
I am leaning towards the nRSP-ST just for having less variables to screw with . . .
